摘要： The present invention is about a method of controlling weeds using the metabolites tenuazonic acid, iso-tenuazonic acid and their salts isolated from the cultures of Alternaria alternata (Fr.) Keissler. The spray of one of these compounds at the rate of 5 to 800 μg/g can cause the main broad leaf, grassy and sedge weeds to hurt, wilt, even dry to death which exhibits herbicidal activity with broad spectrum, quick killing and efficient effect. The addition of adjuvants improves their herbicidal activity.

摘要： The present invention is directed to a polystyrene cation exchange resin catalyst for olefin hydration comprises: monomer units of (a) 7.5 to 11.5 wt % at least one polyvinylaromatic monomer and (b) 88.5 to 92.5 wt % at least one monovinylaromatic monomer; (c) 0.75 to 1.20 SO3H moiety on each aromatic ring of the polymer backbone; and (d) 0.70 to 1.20 halogen on each aromatic ring of the polymer backbone. The present invention also provides a method for preparing the catalyst including the steps of copolymerization, sulfonation, halogenation, and post treatment. Optimization of the copolymer crosslinking degree, sulfonation and halogenation extent enables the catalyst with a balance of catalysis activity and thermal stability.
